<p>After answering on <a href="https://stackoverflow.com/questions/45650/common-files-in-visual-studio-solution#45664">this question</a> I thought it would be nice to collect some tips & tricks for working with MSVS solutions and projects. </p>
<p>Here is my list: </p>
<ul>
<li><p>How to avoid saving new projects
automatically to reduce garbage in
file system.</p>
<p>Uncheck <strong>Tools->Options->Projects and Solutions->Save new projects when created</strong></p></li>
<li><p>How to add common file to multiple
projects without copying it to
project’s directory.</p>
<p>Right click on a project, select <strong>Add->Existing Item->Add as link</strong> (press on small arrow on Add button)</p></li>
<li><p>How to add project to solution
without including it in the build
process</p>
<p>Right click on solution, select <strong>Add->New solution folder</strong>.<br>
Right click on created folder, <strong>select Add->Add existing project</strong></p></li>
<li><p>How to edit project file from Visual
Studio?</p>
<p>Right click on project and select <strong>Unload Project</strong>, right click on unloaded project and select <strong>Edit</strong>.
Or install <a href="http://code.msdn.microsoft.com/PowerCommands" rel="nofollow noreferrer">Power Commands</a> and select <strong>Edit Project File</strong></p></li>
<li><p>How to group files in the project
tree (like auto-generated files for
WinForms controls)</p>
<p>Open project file for editing. </p></li>
</ul>
<pre> Change</pre>
<pre><code><Compile Include="MainFile.cs" />
<Compile Include="SecondaryFile.cs" />
To
<Compile Include="SecondaryFile.cs ">
<DependentUpon> MainFile.cs </DependentUpon>
</Compile>
</code></pre>
<p>Do you have anything else to add?</p>

<p>My users are having an intermittent error when using a Windows Forms application built in VB.NET 3.5. Apparently when they click on the form and the form re-paints, a red 'X' will be painted over the MenuStrip control and the app will crash with the following error. </p>
<p>Has anyone seen this before? Can someone point me in the right direction? </p>

<p>I've used subversion for a while, and used the svnmerge.py script for a while in my old job to manage merges between branches. I believe Subversion 1.5 is now out, and was supposed to have some branch / merge management system integrated with it.</p>
<p>So, can someone give me a quick overview of how to track merges in a branch with Subversion 1.5? Are there any pitfalls with using this support? Do I need to ensure all the team upgrades to 1.5 before using this support?</p>

<p>I need to execute a directory copy upon a user action, but the directories are quite large, so I would like to be able to perform such an action without the user being aware of the time it takes for the copy to complete.</p>
<p>Any suggestions would be much appreciated.</p>

<p>I'm working on a utility which needs to resolve hex addresses to a symbolic function name and source code line number within a binary. The utility will run on Linux on x86, though the binaries it analyzes will be for a MIPS-based embedded system. The MIPS binaries are in ELF format, using DWARF for the symbolic debugging information.</p>
<p>I'm currently planning to fork objdump, passing in a list of hex addresses and parsing the output to get function names and source line numbers. I have compiled an objdump with support for MIPS binaries, and it is working.</p>
<p>I'd prefer to have a package allowing me to look things up natively from the Python code without forking another process. I can find no mention of libdwarf, libelf, or libbfd on python.org, nor any mention of python on dwarfstd.org.</p>
<p>Is there a suitable module available somewhere?</p>

<p>How do I multiply 10 to an <code>Integer</code> object and get back the <code>Integer</code> object?</p>
<p>I am looking for the neatest way of doing this.</p>
<p>I would probably do it this way:
Get int from <code>Integer</code> object, multiply it with the other int and create another Integer object with this int value.</p>
<p>Code will be something like ... </p>
<pre><code>integerObj = new Integer(integerObj.intValue() * 10);
</code></pre>
<p>But, I saw a code where the author is doing it this way: Get the <code>String</code> from the <code>Integer</code> object, concatenate "0" at the end and then get <code>Integer</code> object back by using <code>Integer.parseInt</code></p>
<p>The code is something like this:</p>
<pre><code>String s = integerObj + "0";
integerObj = Integer.parseInt(s);
</code></pre>
<p>Is there any merit in doing it either way?</p>
<p>And what would be the most efficient/neatest way in general and in this case?</p>

<p>I'm working on a program that will be processing files that could potentially be 100GB or more in size. The files contain sets of variable length records. I've got a first implementation up and running and am now looking towards improving performance, particularly at doing I/O more efficiently since the input file gets scanned many times.</p>
<p>Is there a rule of thumb for using <code>mmap()</code> versus reading in blocks via C++'s <code>fstream</code> library? What I'd like to do is read large blocks from disk into a buffer, process complete records from the buffer, and then read more.</p>
<p>The <code>mmap()</code> code could potentially get very messy since <code>mmap</code>'d blocks need to lie on page sized boundaries (my understanding) and records could potentially lie across page boundaries. With <code>fstream</code>s, I can just seek to the start of a record and begin reading again, since we're not limited to reading blocks that lie on page sized boundaries.</p>
<p>How can I decide between these two options without actually writing up a complete implementation first? Any rules of thumb (e.g., <code>mmap()</code> is 2x faster) or simple tests?</p>

<p>In a C# .NET 3.5 app (a mix of WinForms and WPF) I want to let the user select a folder to import a load of data from. At the moment, it's using <code>System.Windows.Forms.FolderBrowserDialog</code> but that's a bit lame. Mainly because you can't type the path into it (so you need to map a network drive, instead of typing a UNC path).</p>
<p>I'd like something more like the <code>System.Windows.Forms.OpenFileDialog</code>, but for folders instead of files. </p>
<p>What can I use instead? A WinForms or WPF solution is fine, but I'd prefer not to PInvoke into the Windows API if I can avoid it.</p>

<p>I'm building a website that requires very basic markup capabilities. I can't use any 3rd party plugins, so I just need a simple way to convert markup to HTML. I might have a total of 3 tags that I'll allow.</p>
<p>What is the best way to convert <code>==Heading==</code> to <code><h2>Heading</h2></code>, or <code>--bold--</code> to <code><b>bold</b></code>? Can this be done simply with Regex, or does somebody have a simple function?</p>
<p>I'm writing this in C#, but examples from other languages would probably work.</p>

<p>We are trying to implement a REST API for an application we have now. We want to expose read/write capabilities for various resources using the REST API. How do we implement the "form" part of this? I get how to expose "read" of our data by creating RESTful URLs that essentially function as method calls and return the data:</p>
<pre><code>GET /restapi/myobject?param=object-id-maybe
</code></pre>
<p>...and an XML document representing some data structure is returned. Fine.</p>
<p>But, normally, in a web application, an "edit" would involve two requests: one to load the current version of the resources and populate the form with that data, and one to post the modified data back. </p>
<p>But I don't get how you would do the same thing with HTTP methods that REST is sort of mapped to. It's a PUT, right? Can someone explain this?</p>
<p>(Additional consideration: The UI would be primarily done with AJAX)</p>
<p>--
Update: That definitely helps. But, I am still a bit confused about the server side? Obviously, I am not simply dealing with files here. On the server, the code that answers the requests should be filtering the request method to determine what to do with it? Is that the "switch" between reads and writes?</p>

<p>If I have a collection of database tables (in an Access file, for example) and need to validate each table in this collection against a rule set that has both common rules across all tables as well as individual rules specific to one or a subset of tables, can someone recommend a good design pattern to look into?</p>
<p>Specifically, I would like to avoid code similar to:</p>
<pre><code>void Main()
{
ValidateTable1();
ValidateTable2();
ValidateTable3();
}
private void ValidateTable1()
{
//Table1 validation code goes here
}
private void ValidateTable2()
{
//Table2 validation code goes here
}
private void ValidateTable3()
{
//Table3 validation code goes here
}
</code></pre>
<p>Also, I've decided to use log4net to log all of the errors and warnings, so that each method can be declared <code>void</code> and doesn't need to return anything. Is this a good idea or would it be better to create some sort of <code>ValidationException</code> that catches all exceptions and stores them in a <code>List<ValidationException></code> before printing them all out at the end?</p>
<p>I did find <a href="http://www.hickorysystems.com/sw_validation.html" rel="noreferrer">this</a>, which looks like it may work, but I'm hoping to actually find some code samples to work off of. Any suggestions? Has anyone done something similar in the past?</p>
<p>For some background, the program will be written in either C# or VB.NET and the tables will more than likely be stored in either Access or SQL Server CE.</p>

<p>So, I did search google and SO prior to asking this question. Basically I have a DLL that has a form compiled into it. The form will be used to display information to the screen. Eventually it will be asynchronous and expose a lot of customization in the dll. For now I just want it to display properly. The problem that I am having is that I use the dll by loading it in a Powershell session. So when I try to display the form and get it to come to the top and have focus, It has no problem with displaying over all the other apps, but I can't for the life of me get it to display over the Powershell window. Here is the code that I am currently using to try and get it to display. I am sure that the majority of it won't be required once I figure it out, this just represents all the things that I found via google.</p>
<pre><code>CLass Blah
{
[DllImport("user32.dll", EntryPoint = "SystemParametersInfo")]
public static extern bool SystemParametersInfo(uint uiAction, uint uiParam, uint pvParam, uint fWinIni);
[DllImport("user32.dll", EntryPoint = "SetForegroundWindow")]
public static extern bool SetForegroundWindow(IntPtr hWnd);
[DllImport("User32.dll", EntryPoint = "ShowWindowAsync")]
private static extern bool ShowWindowAsync(IntPtr hWnd, int cmdShow);
private const int WS_SHOWNORMAL = 1;
public void ShowMessage(string msg)
{
MessageForm msgFrm = new MessageForm();
msgFrm.lblMessage.Text = "FOO";
msgFrm.ShowDialog();
msgFrm.BringToFront();
msgFrm.TopMost = true;
msgFrm.Activate();
SystemParametersInfo((uint)0x2001, 0, 0, 0x0002 | 0x0001);
ShowWindowAsync(msgFrm.Handle, WS_SHOWNORMAL);
SetForegroundWindow(msgFrm.Handle);
SystemParametersInfo((uint)0x2001, 200000, 200000, 0x0002 | 0x0001);
}
}
</code></pre>
<p>As I say I'm sure that most of that is either not needed or even flat out wrong, I just wanted to show the things that I had tried. Also, as I mentioned, I plan to have this be asynchronously displayed at some point which I suspect will wind up requiring a separate thread. Would splitting the form out into it's own thread make it easier to cause it to get focus over the Powershell session? </p>
<hr>
<p>@Joel, thanks for the info. Here is what I tried based on your suggestion:</p>
<pre><code>msgFrm.ShowDialog();
msgFrm.BringToFront();
msgFrm.Focus();
Application.DoEvents();
</code></pre>
<p>The form still comes up <em>under</em> the Powershell session. I'll proceed with working out the threading. I've spawned threads before but never where the parent thread needed to talk to the child thread, so we'll see how it goes.</p>
<p>Thnks for all the ideas so far folks.</p>
<hr>
<p>Ok, threading it took care of the problem. @Quarrelsome, I did try both of those. Neither (nor both together) worked. I am curious as to what is evil about using threading? I am not using Application.Run and I have yet to have a problem. I am using a mediator class that both the parent thread and the child thread have access to. In that object I am using a ReaderWriterLock to lock one property that represents the message that I want displayed on the form that the child thread creates. The parent locks the property then writes what should be displayed. The child thread locks the property and reads what it should change the label on the form to. The child has to do this on a polling interval (I default it to 500ms) which I'm not real happy about, but I could not find an event driven way to let the child thread know that the proerty had changed, so I'm stuck with polling.</p>

<p>My work has a financial application, written in <code>VB.NET</code> with <code>SQL</code>, that several users can be working on at the same time.</p>
<p>At some point, one user might decide to Post the batch of entries that they (and possibly other people) are currently working on.</p>
<p>Obviously, I no longer want any other users to <strong>add</strong>, <strong>edit</strong>, or <strong>delete</strong> entries in that batch <strong>after</strong> the <strong>Post process</strong> has been initiated.</p>
<p>I have already seen that I can lock <strong>all</strong> data by opening the SQL transaction the moment the Post process starts, but the process can be fairly lengthy and I would prefer not to have the Transaction open for the several minutes it might take to complete the function.</p>
<p>Is there a way to lock just the records that I know need to be operated on from VB.NET code?</p>

<p>I have a php server that is running my domain name. For testing purposes I am running an asp.net on a dotted quad IP. I am hoping to link them together via either PHP or some kind of DNS/<code>.htaccess</code> voodoo.</p>
<p>So if I go to <code>www.mydomain.com/test</code> it redirects (but keeps the url of (<code>www.mydomain.com/test</code>) in the browser's address bar and the pages are served by the dotted quad IP asp.net box.</p>

<p>Details:</p>
<ul>
<li>Only disable after user clicks the submit button, but before the posting back to the server</li>
<li>ASP.NET Webforms (.NET 1.1)</li>
<li>Prefer jQuery (if any library at all)</li>
<li>Must be enabled if form reloads (i.e. credit card failed)</li>
</ul>
<p>This isn't a necessity that I do this, but if there is a simple way to do it without having to change too much, I'll do it. (i.e. if there isn't a simple solution, I probably won't do it, so don't worry about digging too deep)</p>

<p>I'm using TortoiseSVN against the SourceForge SVN repository. I'd like to move a file from one folder to another in order to maintain its revision history. Is this possible? If so, how do you do it?</p>
<p>(My current strategy has been to copy the file into the new folder and check it in and then delete the file from the current folder.)</p>

<p>Does this work across all modern browsers and is there a list of browser types that will work with that kind of if statement?</p>

<p>I have a large codebase that targetted Flash 7, with a <em>lot</em> of AS2 classes. I'm hoping that I'll be able to use Flex for any new projects, but a lot of new stuff in our roadmap is additions to the old code.</p>
<p>The syntax for AS2 and AS3 is generally the same, so I'm starting to wonder how hard it would be to port the current codebase to Flex/AS3. I know all the UI-related stuff would be iffy (currently the UI is generated at runtime with a lot of createEmptyMovieClip() and attachMovie() stuff), but the UI and controller/model stuff is mostly separated.</p>
<p>Has anyone tried porting a large codebase of AS2 code to AS3? How difficult is it? What kinds of pitfalls did you run into? Any recommendations for approaches to doing this kind of project?</p>

<p>I am looking for a way to create an int\long representation of an arbitrary alpha-numeric String. Hash codes won't do it, because I can't afford hash collisions i.e. the representation must be unique and repeatable. </p>
<p>The numeric representation will be used to perform efficient (hopefully) compares. The creation of the numeric key will take some time, but it only has to happen once, whereas I need to perform vast numbers of comparisons with it - which will hopefully be much faster than comparing the raw Strings.</p>
<p>Any other idea's on faster String comparison will be most appreciated too...</p>

<p>I'm looking for any way that I can improve the selector performance of a jQuery call. Specifically things like this:</p>
<p>Is <code>$("div.myclass")</code> faster than <code>$(".myclass")</code></p>
<p>I would think it might be, but I don't know if jQuery is smart enough to limit the search by tag name first, etc. Anyone have any ideas for how to formulate a jQuery selector string for best performance?</p>

<p>If I have a </p>
<pre><code><input id="uploadFile" type="file" />
</code></pre>
<p>tag, and a submit button, how do I determine, in IE6 (and above) if a file has been selected by the user.</p>
<p>In FF, I just do:</p>
<pre><code>var selected = document.getElementById("uploadBox").files.length > 0;
</code></pre>
<p>But that doesn't work in IE.</p>

<p>I'm writing my first iPhone app, so I haven't gotten around to figuring out much in the way of debugging.
Essentially my app displays an image and when touched plays a short sound.
When compiling and building the project in XCode, everything builds successfully, but when the app is run in the iPhone simulator, it crashes.</p>
<p>I get the following error:</p>
<pre><code>Application Specific Information:
iPhone Simulator 1.0 (70), iPhone OS 2.0 (5A331)
*** Terminating app due to uncaught exception 'NSUnknownKeyException',
reason: '[<UIView 0x34efd0> setValue:forUndefinedKey:]: this class is not key value
coding-compliant for the key kramerImage.'
</code></pre>
<p>kramerImage here is the image I'm using for the background.</p>
<p>I'm not sure what NSUnknownKeyException means or why the class is not key value coding-compliant for the key.</p>

<p>I'm working on an application where users have to make a call and type a verification number with the keypad of their phone.</p>
<p>I would like to be able to detect if the number they type is correct or not. The phone system does not have access to a list of valid numbers, but instead, it will validate the number against an algorithm (like a credit card number).</p>
<p>Here are some of the requirements :</p>
<ul>
<li>It must be difficult to type a valid random code </li>
<li>It must be difficult to have a valid code if I make a typo (transposition of digits, wrong digit)</li>
<li>I must have a reasonable number of possible combinations (let's say 1M)</li>
<li>The code must be as short as possible, to avoid errors from the user</li>
</ul>
<p>Given these requirements, how would you generate such a number?</p>
<p>EDIT :</p>
<p>@Haaked: The code has to be numerical because the user types it with its phone.</p>
<p>@matt b: On the first step, the code is displayed on a Web page, the second step is to call and type in the code. I don't know the user's phone number.</p>
<p>Followup : I've found several algorithms to <em>check</em> the validity of numbers (See this interesting Google Code project : <a href="http://code.google.com/p/checkdigits/wiki/CheckDigitSystems" rel="nofollow noreferrer">checkDigits</a>).</p>

<p>We have an encryption service that we've exposed over net. tcp. Most of the time, the service is used to encrypt/decrypt strings. However, every now and then, we the need to encrypt large documents (pdf, JPG, bmp, etc.).</p>
<p>What are the best endpoint settings for a scenario like this? Should I accept/return a stream? I've read a lot about this, but no one gives guidance on what to do when the large file doesn't occur frequently.</p>

<p>I have been hearing a lot of good things about DVCS systems, in particular about bazaar. Apart from the concept of distributed repository, I see two main advantages being touted: the merge is better automated, and the rename is handled right.</p>
<p>Could someone please point me at some text explaining how exactly the improvements work? How does bazaar know that I renamed a file? What if I rename two files as part of the same commit? What happens when I refactor by putting half of the file's contents into a new file, re-indenting everything and losing some whitespace in nearly every line?</p>
<p>In other words, I'd like to hear from people using bazaar (or another DVCS) in real life, or from people who know how it (they) works. Is the merge really that much better? And how is it achieved?</p>
<hr>

<p>I am using a class library which represents some of its configuration in .xml. The configuration is read in using the <code>XmlSerializer</code>. Fortunately, the classes which represent the .xml use the <code>XmlAnyElement</code> attribute at which allows me to extend the configuration data for my own purposes without modifying the original class library.</p>
<pre><code><?xml version="1.0" encoding="utf-8"?>
<Config>
<data>This is some data</data>
<MyConfig>
<data>This is my data</data>
</MyConfig>
</Config>
</code></pre>
<p>This works well for deserialization. I am able to allow the class library to deserialize the .xml as normal and the I can use my own <code>XmlSerializer</code> instances with a <code>XmlNodeReader</code> against the internal <code>XmlNode</code>.</p>
<pre><code>public class Config
{
[XmlElement]
public string data;
[XmlAnyElement]
public XmlNode element;
}
public class MyConfig
{
[XmlElement]
public string data;
}
class Program
{
static void Main(string[] args)
{
using (Stream fs = new FileStream(@"c:\temp\xmltest.xml", FileMode.Open))
{
XmlSerializer xser1 = new XmlSerializer(typeof(Config));
Config config = (Config)xser1.Deserialize(fs);
if (config.element != null)
{
XmlSerializer xser2 = new XmlSerializer(typeof(MyConfig));
MyConfig myConfig = (MyConfig)xser2.Deserialize(new XmlNodeReader(config.element));
}
}
}
</code></pre>
<p>I need to create a utility which will allow the user to generate a new configuration file that includes both the class library configuration as well my own configuration, so new objects will be created which were not read from the .xml file. The question is how can I serialize the data back into .xml? </p>
<p>I realize that I have to initially call <code>XmlSerializer.Serialize</code> on my data before calling the same method on the class library configuration. However, this requires that my data is represented by an <code>XmlNode</code> after calling <code>Serialize</code>. What is the best way to serialize an object into an <code>XmlNode</code> using the <code>XmlSerializer</code>?</p>
<p>Thanks,</p>
<p>-kevin</p>
<p>btw-- It looks like an <code>XmlNodeWriter</code> class written by Chris Lovett was available at one time from Microsoft, but the links are now broken. Does anyone know of an alternative location to get this class?</p>

<p>I understand how I can change the <code>dns</code> settings for my domains by editing my bind configs, when I run my own name-servers. I know that I can define the name-servers with my registrar via their online control panels. But I have no idea how that part works...</p>
<p>How does my registrar store the data about the name-servers? Is it something clever, like them having the authority to store NS records in the root name-servers?</p>
<p>I'm confused by this part, can anyone explain?</p>

ERROR: cross-database references are not implemented:

<p>Any ideas on how to implement tab completion for a .NET (C#) Console Application?
And I mean within an application that is run and then loops for user input (like if you run ftp.exe without any arguments), like this: </p>
<pre><code> string line = string.Empty;
while (line != "exit")
{
//do something here
Console.ReadLine();
}
</code></pre>
<p>I know I probably couldn't actually use readline, but I would like to be able to do tab completion at that same point where you retrieve input from the user.</p>

<p>After lots of attempts and search I have never found a satisfactory way to do it with CSS2.</p>
<p>A simple way to accomplish it is to wrap it into a handy <code><table></code> as shown in the sample below. Do you know how to do it avoiding table layouts and also avoiding quirky tricks?</p>
<p><div class="snippet" data-lang="js" data-hide="false" data-console="true" data-babel="false">
<div class="snippet-code">
<pre class="snippet-code-css lang-css prettyprint-override"><code>table {
margin: 0 auto;
}</code></pre>
<pre class="snippet-code-html lang-html prettyprint-override"><code><table>
<tr>
<td>test<br/>test</td>
</tr>
</table></code></pre>
</div>
</div>
</p>
<hr />
<p>What I want to know is how to do it without a fixed width and also being a block.</p>

<p>I'm trying to perform a SQL query through a linked SSAS server. The initial query works fine:</p>
<pre><code>SELECT "Ugly OLAP name" as "Value"
FROM OpenQuery( OLAP, 'OLAP Query')
</code></pre>
<p>But if I try to add:</p>
<pre><code>WHERE "Value" > 0
</code></pre>
<p>I get an error</p>
<blockquote>
<p>Invalid column name 'Value'</p>
</blockquote>
<p>Any ideas what I might be doing wrong?</p>
<hr>
<p>So the problem was that the order in which elements of the query are processed are different that the order they are written. According to this source:</p>
<p><a href="http://blogs.x2line.com/al/archive/2007/06/30/3187.aspx" rel="noreferrer">http://blogs.x2line.com/al/archive/2007/06/30/3187.aspx</a></p>
<p>The order of evaluation in MSSQL is:</p>
<ol>
<li>FROM</li>
<li>ON</li>
<li>JOIN</li>
<li>WHERE</li>
<li>GROUP BY</li>
<li>HAVING</li>
<li>SELECT</li>
<li>ORDER BY</li>
</ol>
<p>So the alias wasn't processed until after the WHERE and HAVING clauses.</p>

<p>We have a SQL Server 2005 SP2 machine running a large number of databases, all of which contain full-text catalogs. Whenever we try to drop one of these databases or rebuild a full-text index, the drop or rebuild process hangs indefinitely with a MSSEARCH wait type. The process can’t be killed, and a server reboot is required to get things running again. Based on a Microsoft forums post<a href="http://forums.microsoft.com/MSDN/ShowPost.aspx?PostID=2681739&SiteID=1" rel="noreferrer">1</a>, it appears that the problem might be an improperly removed full-text catalog. Can anyone recommend a way to determine which catalog is causing the problem, without having to remove all of them?</p>
<p><a href="http://forums.microsoft.com/MSDN/ShowPost.aspx?PostID=2681739&SiteID=1" rel="noreferrer">1</a> [<a href="http://forums.microsoft.com/MSDN/ShowPost.aspx?PostID=2681739&SiteID=1]" rel="noreferrer">http://forums.microsoft.com/MSDN/ShowPost.aspx?PostID=2681739&SiteID=1]</a>
“Yes we did have full text catalogues in the database, but since I had disabled full text search for the database, and disabled msftesql, I didn't suspect them. I got however an article from Microsoft support, showing me how I could test for catalogues not properly removed. So I discovered that there still existed an old catalogue, which I ,after and only after re-enabling full text search, were able to delete, since then my backup has worked”</p>

<p>What is the syntax for placing constraints on multiple types? The basic example:</p>
<pre><code>class Animal<SpeciesType> where SpeciesType : Species
</code></pre>
<p>I would like to place constraints on both types in the following definition such that <code>SpeciesType</code> must inherit from <code>Species</code> and <code>OrderType</code> must inherit from <code>Order</code>:</p>
<pre><code>class Animal<SpeciesType, OrderType>
</code></pre>

<p>If you've used Oracle, you've probably gotten the helpful message "ORA-00942: Table or view does not exist". Is there a legitimate technical reason the message doesn't include the name of the missing object? </p>
<p>Arguments about this being due to security sound like they were crafted by the TSA. If I'm an attacker, I'd know what table I just attempted to exploit, and be able to interpret this unhelpful message easily. If I'm a developer working with a complex join through several layers of application code, it's often very difficult to tell.</p>
<p>My guess is that when this error was originally implemented, someone neglected to add the object name, and now, people are afraid it will break compatibility to fix it. (Code doing silly things like parsing the error message will be confused if it changes.)</p>
<p>Is there a developer-friendly (as opposed to recruiting your DBA) way to determine the name of the missing table?</p>
<hr>
<p>Although I've accepted an answer which is relevant to the topic, it doesn't really answer my question: <em>Why isn't the name part of the error message?</em> If anyone can come up with the real answer, I'll be happy to change my vote.</p>

<p>I am using a perl script to POST to Google Appengine application. I post a text file containing some XML using the -F option.</p>
<p><a href="http://www.cpan.org/authors/id/E/EL/ELIJAH/bget-1.1" rel="nofollow noreferrer">http://www.cpan.org/authors/id/E/EL/ELIJAH/bget-1.1</a></p>
<p>There is a version 1.2, already tested and get the same issue. The post looks something like this.</p>
<pre><code>Host: foo.appspot.com
User-Agent: lwp-request/1.38
Content-Type: text/plain
Content-Length: 202
<XML>
<BLAH>Hello World</BLAH>
</XML>
</code></pre>
<p>I have modified the example so the 202 isn't right, don't worry about that. On to the problem. The Content-Length matches the number of bytes on the file, however unless I manually increase the Content-Length it does not send all of the file, a few bytes get truncated. The number of bytes truncated is not the same for files of different sizes. I used the -r option on the script and I can see what it is sending and it is sending all of the file, but Google Appengine self.request.body shows that not everything is received. I think the solution is to get the right number for Content-Length and apparently it isn't as simple as number of bytes on the file or the perl script is mangling it somehow.</p>
<p>Update:
Thanks to Erickson for the right answer. I used printf to append characters to the end of the file and it always truncated exactly the number of lines in the file. I suppose I could figure out what is being added by iterating through every character on the server side but not worth it. This wasn't even answered over on the google groups set up for app engine!</p>

<p>I have ms sql databases that grow very large. Upon examination I find that there is a bunch of unused space in certain tables. I don't do many physical deletes, so I don't think that its just deleted records. DBCC SHRINK doesn't make the file smaller. But, if I dump the table to a new, empty database, the size goes down about 80%. Instead of the 7gb I have in this table in the current database, I end up with about 1.5gb in the fresh database. Its as if sql server is allocating too much memory. Anyone encountered this before? I'd like to be able to shrink the table by removing unused allocated space without having to create a whole new database.</p>
<p>Additional information:</p>
<p>Full recovery model used. I'll try rebuilding the indexes, i think its been a while. ldf's are shrunk daily using some wacky stored proc that truncates them.</p>

<p>Is there an easy way to read an entire Access file (.mdb) into a DataSet in .NET (specifically C# or VB)?</p>
<p>Or at least to get a list of tables from an access file so that I can loop through it and add them one at a time into a DataSet?</p>

<p>In my web application I include all of my JavaScripts as js files that are embedded resources in the assembly, and add them to the page using <code>ClientScriptManager.GetWebResourceUrl()</code>. However, in some of my js files, I have references to other static assets like image urls. I would like to make those assembly resources as well. Is there a way to tokenize the reference to the resource? e.g.</p>
<pre><code>this.drophint = document.createElement('img');
this.drophint.src = '/_layouts/images/dragdrophint.gif';
</code></pre>
<p>Could become something like:</p>
<pre><code>this.drophint = document.createElement('img');
this.drophint.src = '{resource:assembly.location.dragdrophint.gif}';
</code></pre>

<p>Today I had a coworker suggest I refactor my code to use a label statement to control flow through 2 nested for loops I had created. I've never used them before because personally I think they decrease the readability of a program. I am willing to change my mind about using them if the argument is solid enough however. What are people's opinions on label statements?</p>

<p>If I have an XElement that has child elements, and if I remove a child element from the parent, removing all references between the two, will the child XElement have the same namespaces as the parent?</p>
<p>In other words, if I have the following XML:</p>
<pre><code><parent xmlns:foo="abc">
<foo:child />
</parent>
</code></pre>
<p>and I remove the child element, will the child element's xml look like</p>
<pre><code><child xmlns="abc" />
</code></pre>
<p>or like </p>
<pre><code><child />

<p>Name the design considerations in deciding between use of a <a href="http://en.wikipedia.org/wiki/Singleton_pattern" rel="noreferrer">singleton</a> versus a static class. In doing this, you're kind of forced to contrast the two, so whatever contrasts you can come up with are also useful in showing your thought process! Also, every interviewer likes to see illustrative examples. :)</p>

<p>How do I do backups in MySQL? </p>
<p>I'm hoping there'll be something better than just running mysqldump every "x" hours.</p>
<p>Is there anything like SQL Server has, where you can take a full backup each day, and then incrementals every hour, so if your DB dies you can restore up to the latest backup?</p>
<p>Something like the DB log, where as long as the log doesn't die, you can restore up to the exact point where the DB died?</p>
<p>Also, how do these things affect locking?
I'd expect the online transactions to be locked for a while if I do a mysqldump.</p>

<p>I have been tasked with going through a number of ColdFusion sites that have recently been the subject of a rather nasty SQL Injection attack. Basically my work involves adding <code><cfqueryparam</code>> tags to all of the inline sql. For the most part I've got it down, but can anybody tell me how to use cfqueryparam with the LIKE operator?</p>
<p>If my query looks like this:</p>
<pre><code>select * from Foo where name like '%Bob%'
</code></pre>
<p>what should my <code><cfqueryparam</code>> tag look like?</p>

<p>We have the requirement to take a form submission and save some data, then redirect the user to a page offsite, but in redirecting, we need to "submit" a form with POST, not GET.</p>
<p>I was hoping there was an easy way to accomplish this, but I'm starting to think there isn't. I think I must now create a simple other page, with just the form that I want, redirect to it, populate the form variables, then do a body.onload call to a script that merely calls document.forms[0].submit();</p>
<p>Can anyone tell me if there is an alternative? We might need to tweak this later in the project, and it might get sort of complicated, so if there was an easy we could do this all non-other page dependent that would be fantastic.</p>
<p>Anyway, thanks for any and all responses.</p>

<p>From what I can gather, there are three categories:</p>
<ol>
<li>Never use <code>GET</code> and use <code>POST</code></li>
<li>Never use <code>POST</code> and use <code>GET</code></li>
<li>It doesn't matter which one you use.</li>
</ol>
<p>Am I correct in assuming those three cases? If so, what are some examples from each case?</p>

While it's possible to use goto to produce unmaintainable, sprawling code, it nevertheless remains in <a href="http://msdn.microsoft.com/en-us/library/13940fs2(VS.71).aspx" rel="noreferrer">modern programming languages</a>. Even the advanced <a href="http://en.wikipedia.org/wiki/Goto#Continuations" rel="noreferrer">continuation</a> control structure in Scheme can be described as a sophisticated goto.</p>
<p>What circumstances warrant the use of goto? When is it best to avoid?</p>
<p>As a follow-up question: C provides a pair of functions, setjmp() and longjmp(), that provide the ability to goto not just within the current stack frame but within any of the calling frames. Should these be considered as dangerous as goto? More dangerous?</p>
<hr />
<p>Dijkstra himself regretted that title, for which he was not responsible. At the end of <a href="http://www.cs.utexas.edu/%7EEWD/transcriptions/EWD13xx/EWD1308.html" rel="noreferrer">EWD1308</a> (also <a href="http://www.cs.utexas.edu/%7EEWD/ewd13xx/EWD1308.PDF" rel="noreferrer">here</a> .pdf) he wrote:</p>
<blockquote>
<p>Finally a short story for the record.
In 1968, the Communications of the ACM
published a text of mine under the
title "<em>The goto statement considered
harmful</em>", which in later years would
be most frequently referenced,
regrettably, however, often by authors
who had seen no more of it than its
title, which became a cornerstone of
my fame by becoming a template: we
would see all sorts of articles under
the title "X considered harmful" for
almost any X, including one titled
"Dijkstra considered harmful". But
what had happened? I had submitted a
paper under the title "<em><strong>A case against
the goto statement</strong></em>", which, in order
to speed up its publication, the
editor had changed into a "letter to
the Editor", and in the process he had
given it a new title of his own
invention! The editor was Niklaus
Wirth.</p>
</blockquote>
<p>A well thought out classic paper about this topic, to be matched to that of Dijkstra, is <a href="http://www.clifford.at/cfun/cliffdev/p261-knuth.pdf" rel="noreferrer">Structured Programming with go to Statements</a>, by Donald E. Knuth. Reading both helps to reestablish context and a non-dogmatic understanding of the subject. In this paper, Dijkstra's opinion on this case is reported and is even more strong:</p>
<blockquote>
<p><em>Donald E. Knuth:</em> I believe that by presenting such a
view I am not in fact disagreeing
sharply with Dijkstra's ideas, since
he recently wrote the following:
"Please don't fall into the trap of
believing that I am terribly
dogmatical about [the go to
statement]. <strong>I have the uncomfortable
feeling that others are making a
religion out of it, as if the
conceptual problems of programming
could be solved by a single trick, by
a simple form of coding discipline!</strong>"</p>

<p>I have a DotNetNuke site where my main logo is a PNG file using transparency. I tried GIF but the quality wasn't good enough.</p>
<p>Anyways it worked great on IE7 but I just saw my site in IE6 and noticed that the transparency isn't working with my logo.</p>
<p>Does anyone know of a quick way to fix this in a DotNetNuke portal?</p>

I suppose this is the driver I would use to connect from a Java app (on windows) to DB2 on the mainframe?</p>

<p>For the following HTML:</p>
<pre><code><form name="myForm">
<label>One<input name="area" type="radio" value="S" /></label>
<label>Two<input name="area" type="radio" value="R" /></label>
<label>Three<input name="area" type="radio" value="O" /></label>
<label>Four<input name="area" type="radio" value="U" /></label>
</form>
</code></pre>
<p>Changing from the following JavaScript code:</p>
<pre><code>$(function() {
var myForm = document.myForm;
var radios = myForm.area;
// Loop through radio buttons
for (var i=0; i<radios.length; i++) {
if (radios[i].value == "S") {
radios[i].checked = true; // Selected when form displays
radioClicks(); // Execute the function, initial setup
}
radios[i].onclick = radioClicks; // Assign to run when clicked
}
});
</code></pre>
<p>Thanks</p>
<p>EDIT: The response I selected answers the question I asked, however I like the answer that uses <code>bind()</code> because it also shows how to distinguish the group of radio buttons</p>

<p>When designing a database to use MVCC (Multi-Version Concurrency Control), you create tables with either a boolean field like "IsLatest" or an integer "VersionId", and you never do any updates, you only insert new records when things change. </p>
<p>MVCC gives you automatic auditing for applications that require a detailed history, and it also relieves pressure on the database with regards to update locks. The cons are that it makes your data size much bigger and slows down selects, due to the extra clause necessary to get the latest version. It also makes foreign keys more complicated.</p>
<p>(Note that I'm <em>not</em> talking about the native MVCC support in RDBMSs like SQL Server's snapshot isolation level)</p>
<p>This has been discussed in other posts here on Stack Overflow. [todo - links]</p>
<p>I am wondering, which of the prevalent entity/ORM frameworks (Linq to Sql, ADO.NET EF, Hibernate, etc) can cleanly support this type of design? This is a major change to the typical ActiveRecord design pattern, so I'm not sure if the majority of tools that are out there could help someone who decides to go this route with their data model. I'm particularly interested in how foreign keys would be handled, because I'm not even sure of the best way to data model them to support MVCC.</p>

<p>On Fedora Core 7, I'm writing some code that relies on <code>ARG_MAX</code>. However, even if I <code>#include <limits.h></code>, the constant is still not defined. My investigations show that it's present in <code><sys/linux/limits.h></code>, but this is supposed to be portable across Win32/Mac/Linux, so directly including it isn't an option. What's going on here?</p>

<p>I'm just curious how most people make their ASP.NET pages printer-friendly? Do you create a separate printer-friendly version of the ASPX page, use CSS or something else? How do you handle situations like page breaks and wide tables?</p>
<p>Is there one elegant solution that works for the majority of the cases? </p>

<p>I have a regex call that I need help with.</p>
<p>I haven't posted my regex, because it is not relevant here.
What I want to be able to do is, during the Replace, I also want to modify the ${test} portion by doing a Html.Encode on the entire text that is effecting the regex.</p>
<p>Basically, wrap the entire text that is within the range of the regex with the bold tag, but also Html.Encode the text inbetween the bold tag.</p>
<pre><code>RegexOptions regexOptions = RegexOptions.Compiled | RegexOptions.IgnoreCase;
text = Regex.Replace(text, regexBold, @"<b>${text}</b>", regexOptions);
</code></pre>

<p>I want to run a web application on php and mysql, using the CakePHP framework. And to keep the threshold of using the site at a very low place, I want to not use the standard login with username/password. (And I don't want to hassle my users with something like OpenID either. Goes to user type.)</p>
<p>So I'm thinking that the users shall be able to log in by sending an email to [email protected] with no subject or content required. And they will get, in reply, an email with a link that will log them in (it will contain a hash). Also I will let the users do some actions without even visiting the site at all, just send an email with [email protected] and the command will be carried out. I will assume that the users and their email providers takes care of their email account security and as such there is no need for it on my site.</p>
<p>Now, how do I go from an email is sent to an account that is not read by humans to there being fired off some script (basically a "dummy browser client" calls an url( and the cakephp will take care of the rest)?</p>
<hr>
<p>I have never used a cron job before, but I do think I understand their purpose or how they generally work. I can not have the script be called by random people visiting the site, as that solution won't work for several reasons. I think I would like to hear more about the possibility of having the script be run as response to an email coming in, if anyone has any input at all on that. If it's run as a cron job it would only check every X minutes and users would get a lag in their response (if i understand it correctly). </p>
<p>Since there will be different email addresses for different commands, like <strong>login</strong>@domain.com and I know what to do and how to do it to based on the sender email, i dont even need the content, subject or any other headers from the email.</p>
<hr>
<p>There is a lot of worry about security of this application, I understand the issues, but without giving away my concept, I dont think it is a big issue for what I am doing. Also about the usability issue, there really isnt any. It's just gonna be login to provide changes on a users profile if/when they need that and one other command. And this is the main email and is very easy to remember and the outset of this whole concept.</p>

<p>Occasionally, on a ASP (classic) site users will get this error:</p>
<pre><code>[DBNETLIB][ConnectionRead (recv()).]General network error.
</code></pre>
<p>Seems to be random and not connected to any particular page. The SQL server is separated from the web server and my guess is that every once and a while the "link" goes down between the two. Router/switch issue... or has someone else ran into this problem before?</p>

<p>I'm working on a C# winforms application (VS.NET 2008, .NET 3.5 sp 1). I have a search field on a form, and rather than have a label next to the search field I'd like to show some grey text in the background of the search field itself ('Search terms', for example). When the user starts entering text in the search field the text should disappear. How can I achieve this?</p>

LAST-NAME PIC X(15) VALUE SPACES.
FULL-NAME PIC X(31) VALUE SPACES.
</code></pre>
<p>If <code>FIRST-NAME = 'JOHN '</code> and <code>LAST-NAME = 'DOE '</code>, how can I get:</p>
<pre><code>FULL-NAME = 'JOHN DOE '

<p>as opposed to:</p>
<pre><code>FULL-NAME = 'JOHN DOE '

<p>I have a situation where I might have multiple instances of a program running at once, and it's important that just one specific function not be executing in more than one of these instances at once.</p>
<p>Is this the proper way to use a mutex to prevent this from happening?</p>
<pre><code>lock (this.GetType()) {
_log.Info("Doing Sync");
DoSync();
_log.Info("Sync Completed");
}
</code></pre>

<p>What is the proper way to minimize a WinForms app to the system tray? </p>
<p>Note: minimize to <strong><em>system tray</em></strong>; on the right side of the taskbar by the clock. I'm not asking about minimizing to taskbar, which is what happens when you hit the "minus" button on the window.</p>
<p>I've seen hackish solutions like, "minimize, set ShowInTaskbar = false, then show your NotifyIcon."</p>
<p>Solutions like that are hackish because the app doesn't appear to minimize to the tray like other apps, the code has to detect when to set ShowInTaskbar = true, among other issues.</p>
<p>What's the proper way to do this?</p>

<p>Suppose I want to implement a reasonably efficient 'keyword recognition algorithm', that is first given a list of keyword, and must then answer if another given word was in the list. </p>
<p>In an imperative language, I would store the keywords in a tree (one node per character). Then, when receiving a word to test, I would scan my tree to test if the word is a keyword.</p>
<p>I'd like to understand how such an algorithm would be coded in a functional language. How does one get the benefits of 'stateless' programming while keeping the efficiency of 'imperative' algorithms. Isn't it necessary to store the tree somewhere between the lookups if you don't want to rebuild it each time? </p>

<p>I'm having some inheritance issues as I've got a group of inter-related abstract classes that need to all be overridden together to create a client implementation. Ideally I would like to do something like the following:</p>
<pre><code>abstract class Animal
{
public Leg GetLeg() {...}
}
abstract class Leg { }
class Dog : Animal
{
public override DogLeg Leg() {...}
}
class DogLeg : Leg { }
</code></pre>
<p>This would allow anyone using the Dog class to automatically get DogLegs and anyone using the Animal class to get Legs. The problem is that the overridden function has to have the same type as the base class so this will not compile. I don't see why it shouldn't though, since DogLeg is implicitly castable to Leg. I know there are plenty of ways around this, but I'm more curious why this isn't possible/implemented in C#.</p>
<p><strong>EDIT</strong>: I modified this somewhat, since I'm actually using properties instead of functions in my code. </p>
<p><strong>EDIT</strong>: I changed it back to functions, because the answer only applies to that situation (covariance on the value parameter of a property's set function <strong>shouldn't</strong> work). Sorry for the fluctuations! I realize it makes a lot of the answers seem irrelevant.</p>

<p>I have an Image control with it's source bound to a property on an object(string url to an image). After making a service call, i update the data object with a new URL. The exception is thrown after it leaves my code, after invoking the PropertyChanged event.</p>
<p>The data structure and the service logic are all done in a core dll that has no knowledge of the UI. How do I sync up with the UI thread when i cant access a Dispatcher? </p>
<p>PS: Accessing Application.Current.RootVisual in order to get at a Dispatcher is not a solution because the root visual is on a different thread(causing the exact exception i need to prevent). </p>
<p>PPS: This only is a problem with the image control, binding to any other ui element, the cross thread issue is handled for you.</p>

<p>I'm looking at working on a project which uses C#.NET (sitting on a windows box) as the primary language and PostgreSQL as the backend database (backend is sitting on a linux box). I've heard that ODBC.NET allows for easy integration of these two components. </p>
<p>Has anyone had experience actually setting C# and PostgreSQL up to work together? If so, do you have any suggestions about how to go about it, issues you've found, etc.?</p>

<p>Does anyone have any tips or gotcha moments to look out for when trying to migrate MySQL tables from the the default case-insenstive swedish or ascii charsets to utf-8? Some of the projects that I'm involved in are striving for better internationalization and the database is going to be a significant part of this change.</p>
<p>Before we look to alter the database, we are going to convert each site to use UTF-8 character encoding (from least critical to most) to help ensure all input/output is using the same character set.</p>
<p>Thanks for any help</p>

<p>I originally asked <a href="https://stackoverflow.com/questions/46933/why-doesnt-inheritance-work-the-way-i-think-it-should-work">this question</a>, but in finding an answer, discovered that my original problem was a lack of support in C# for covariance on inherited methods' return types. After discovering that, I became curious as to what languages <em>do</em> support this feature.</p>
<p>I will accept the answer of whoever can name the most.</p>
<p><strong>EDIT</strong>: John Millikin correctly pointed out that lots of dynamic languages support this. To clarify: </p>
<p><strong>I am only looking for static/strongly typed languages.</strong></p>

<p>I've somehow managed to get an SVN repository into a bad state. I've moved a directory and now I can't commit it in its new location.</p>
<p>As far as <code>svn status</code> is concerned, the directory is unknown (the name of the directory is <code>type</code>).</p>
<pre>
$ svn status
? type
</pre>
<p>When I try to add the directory, the server says it already exists.</p>
<pre>
$ svn add type
svn: warning: 'type' is already under version control
</pre>
<p>If I try to update the directory, it's gone again.</p>
<pre>
$ svn update type
svn: '.' is not under version control
</pre>
<p>If I try to commit it, the server complains that it's old parent directory no longer exists.</p>
<pre>
$ svn commit type -m "Moving type"
svn: Commit failed (details follow):
svn: '/prior/trunk/src/nyu/prior/cvc3/theorem_prover/expression' path not found
</pre>
<p>To add to the mystery, the contents of the directory are marked as modified.</p>
<pre>
$ svn status type
A + type
M + type/IntegerType.java
M + type/BooleanType.java
M + type/Type.java
M + type/RationalRangeType.java
M + type/RationalType.java
M + type/IntegerRangeType.java
</pre>
<p>If I try to update from within the directory, I get this.</p>
<pre>
$ cd type
$ svn update
svn: Two top-level reports with no target
</pre>
<p>Committing from within the directory gives the same <code>path not found</code> error as above.</p>
<p>What's going on and how do I fix it?</p>
<p>EDIT: @Rob Oxspring caught me out: I got too aggressive moving things around in Eclipse.</p>
<p>UPDATE: I'm accepting @Rob Oxspring's answer of "don't do that/just start over" and taking his advice. I'd still be interested if anybody could tell me: (a) what the above error messages <em>mean</em> precisely and (b) how to actually <em>fix</em> the problem.</p>

<p>Printf got added to Java with the 1.5 release but I can't seem to find how to send the output to a string rather than a file (which is what sprintf does in C). Does anyone know how to do this? </p>

<p>I'm looking to convert a SQL like statement on the fly to the equivalent regex i.e. </p>
<pre><code>LIKE '%this%'
LIKE 'Sm_th'
LIKE '[C-P]arsen'
</code></pre>
<p>What's the best approach to doing this?</p>
<p>P.S. I'm looking to do this on the .Net Framework (C#).</p>
